Description

一种衣物处理装置及控制方法 技术领域
本发明属于衣物处理设备领域，涉及一种衣物处理装置及控制方法。
背景技术
干衣机是利用电加热来使洗好的衣物中的水分及时蒸发干燥的清洁类家用电器。洗干一体机是一种在全自动衣物处理设备基础上增加烘干功能，融合洗衣、甩干、烘干多种功能于一体的智能化新型衣物处理设备。
无论是干衣机还是洗干一体机，其干衣过程主要是通过向桶体内鼓入热干状态的烘干风，将衣物上的水分带出，实现干燥衣物的目的。这种类型的衣物处理设备特别适用于北方的冬季和南方的“回南天”衣物难干的情况。
滚筒式洗干一体机越来越受到用户的青睐，行业内也越来越注重烘干性能的开发。目前，水冷式滚筒洗干一体衣机在烘干过程中需将与衣物进行热交换后的湿热烘干风进行去湿。去湿采用的冷却源可以是冷却水冷或者冷却风，冷却源的供应方式有持续型、定时型，而没有考虑到冷却源的温度对冷却效果的影响，如，冷却源温度较低，供应较少量的冷却源即可达到冷却效果，从而减少冷却源的使用，减少资源浪费。
有鉴于此特提出本发明。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
实施例一
如图1-2所示，一种衣物处理装置，包括用于烘干衣物的烘干系统111和为烘干系统111提供冷却源的冷却系统，冷却系统上设有流量调节装置和温度检测装置100，衣物处理装置根据温度检测装置100检测的冷却源的温度控制流量调节装置调节冷却源的流量。
衣物处理装置可以是干衣机或者洗干一体机。冷却源可以是冷却风也可以是冷却水。
烘干系统111开启后，在冷却源的温度较低时，较小流量的冷却源即可实现对烘干风的冷凝，如果在该情况下，仍然采用大流量的冷却源进行冷却，则造成资源的浪费。
本发明通过设置温度检测装置和流量调节装置，根据冷却源的温度控制流量调节装置调节冷却源的流量，实现冷却源的温度不同时采用不同的流量，既满足冷凝效率，又节约用水、用电。
该衣物处理装置的控制方法，衣物处理装置根据温度检测装置100检测的冷却源的温度控制流量调节装置调节冷却源的流量。当冷却源温度低时，控制流量调节装置调小冷却源的流量，当冷却源温度高时，调大冷却源的流量。
进一步的方案，冷却系统具有与烘干系统111的烘干风进行热交换的冷却部108，所述温度检测装置100设置于冷却部108的上游，衣物处理装置根据温度检测装置100检测的冷却部108上游的冷却源温度控制流量调节装置调节冷却源的流量。
将温度检测装置100设置在冷却部108的上游，温度检测装置100检测换热前的冷却源的温度，实现根据换热前的冷却源的温度控制流量调节装置调节冷却源的流量，由于冷却源的初始温度对冷却效果的影响最大，因此，通过判断冷却源的初始温度控制流量调节装置调节冷却源的流量，在对烘干风较好的冷却、除湿的同时降低成本。该衣物处理装置的控制方法，衣物处理装置根据温度检测装置100检测的冷却部108上游的冷却源温度控制流量调节装置调节冷却源的流量。

其中，流量检测单元102可以为流量传感器。
流量检测单元102反馈冷却源的流量值，衣物处理装置判断反馈的流量值是否等于目标流量值，如果否，则控制流量调节装置调节冷却源的流量，直至调节至目标流量值后停止，如果是，则保持不变。
实施例二

当流量调节阀101开度较大时，冷却源的流量大，反之，流量小。当冷却源温度低时，控制流量调节阀101开度减小，当冷却源温度高时，控制流量调节阀101开度增加。
